Ubuntu Live CD not booting

Asked by 0gl

Hello there,

I've downloaded and burnt the right Ubuntu Live CD (7.10), restarted, changed boot device from harddisk to CDROM in BIOS... But right after the restart the screen turns black and I have to restart my computer. Rebooting has not been the solution, and the other CDROM device turns out just as negative.
I do get the line: ISOLINUX Debian (c) [etc] starting...
If I have the patience to wait long enough, I get a funny square box message (most probably still in BIOS and not from the CD) containing what appears to be hexadecimal values followed by the all-feared ERR message. Pressing ESC pops up a second box, containting some other values.

Maybe I shoud add those.

"#1:
Data_______________________________Prog 0, drive 9F

  : :
  : :
  : :
0: 0.0 :
1: 0.0 :
2: 0.0 0:ffffffff.5
3: c00000.1 1: 121d.15

err 8
ip 11d4: 10.7"

Excuse my ASCII skills.

The other box is similar, with the line [3: c000 ... 1d.15] removed, and the last line: "ip 6ab: 2c.7"

Does anybody have any idea what causes this problem? thank you in advance.

The CD seemed to be corrupted. Try to test (for example try to boot it in another computer). Try to check MD5Sum of downloaded ISO file - https://help.ubuntu.com/community/HowToMD5SUM

Tried it on another computer and it worked just fine. So the CD is not the problem I think.

So try to boot another CD (e.g. Windows Install CD) - maybe something is corrupted with your computer/bios...

Also please send some information about your hardware.

Problem solved.

It's kind of a weird problem - how the hell did it work on the other machine? well anyway - tried some 100s of different Linux distro's - Debian, Kubuntu, PCLOS, Fedora - until I called for my brother, who had this Feisty Fawn copy burnt with a simple download.com program. THAT one worked immediately. Turns out I've been burning too fast.
So, if anyone is reading this, try to consider reburning your downloaded live CD and burn it at 4x speed instead of the hasty 10xs.

Thanks for the attention, Vojtech.
